We've been keeping an eye on Dell's discontinued CableCARD systems since they first introduced them on the XPS 410s because they were a relatively cheap way to get HD recording on a reasonably-priced desktop. Well, fantastic news! Chris Lanier says that Dell's reintroduced the CableCARD option on their XPS 420s, which you can customize and get out the door starting at about a thousand bucks. According to Dell, this is a "functional upgrade to the platform", which means you'll be able to get the CableCARD on this line for the foreseeable future. Sounds like a cheap alternative to our set-top-box wishlist item. [Dell via Chris Lanier]
